People in this middle place have sustained traumatic brain injuries or are the victims of stroke or degenerative diseases, such as Alzheimer’s and Parkinson’s. Many are oblivious to the outside world, and their doctors believe they are incapable of thought. But a sizeable number are experiencing something different: intact minds adrift deep within damaged brains and bodies. Following Owen’s journey of exciting medical discovery, Into the Gray Zone asks some tough and terrifying questions, such as: What is life like for these patients? What can their families and friends do to help them? What are the ethical implications for religious organizations, politicians, the Right to Die movement, and even insurers? And perhaps most intriguing of all: in defining what a life worth living is, are we too concerned with the physical and not giving enough emphasis to the power of thought? What, truly, defines a satisfying life?

    In the great halls of science, dogma holds that Darwin's theory of natural selection explains every branch on the tree of life: which species thrive, which wither away to extinction, and what features each evolves. But can adaptation by natural selection really account for everything we see in nature? Yale University ornithologist Richard Prum--reviving Darwin's own views--thinks not. Deep in tropical jungles around the world are birds with a dizzying array of appearances and mating displays: Club-winged Manakins who sing with their wings, Great Argus Pheasants who dazzle prospective mates with a four-foot-wide cone of feathers covered in golden 3D spheres, Red-capped Manakins who moonwalk. In thirty years of fieldwork, Prum has seen numerous display traits that seem disconnected from, if not outright contrary to, selection for individual survival. To explain this, he dusts off Darwin's long-neglected theory of sexual selection in which the act of choosing a mate for purely aesthetic reasons--for the mere pleasure of it--is an independent engine of evolutionary change. Mate choice can drive ornamental traits from the constraints of adaptive evolution, allowing them to grow ever more elaborate. It also sets the stakes for sexual conflict, in which the sexual autonomy of the female evolves in response to male sexual control. Most crucially, this framework provides important insights into the evolution of human sexuality, particularly the ways in which female preferences have changed male bodies, and even maleness itself, through evolutionary time. The Evolution of Beauty presents a unique scientific vision for how nature's splendor contributes to a more complete understanding of evolution and of ourselves.

    Traveling through the dizzying expanse of geologic time—from prehistoric art in Norwegian sea caves, to the blue depths of the Greenland ice cap, to a deep-sunk "hiding place" where nuclear waste will be stored for 100,000 years to come—Underland takes us on an extraordinary journey into our relationship with darkness, burial, and what lies beneath the surface of both place and mind.Global in its geography and written with great lyricism, Underland speaks powerfully to our present moment. At once ancient and urgent, this is a book that will change the way you see the world.

    New technologies have revealed secrets locked in prehistoric bones that no one could have previously predicted. We can now work out the color of dinosaurs, the force of their bite, their top speeds, and even how they cared for their young.Remarkable new fossil discoveries—giant sauropod dinosaur skeletons in Patagonia, dinosaurs with feathers in China, and a tiny dinosaur tail in Burmese amber—remain the lifeblood of modern paleobiology. Thanks to advances in technologies and methods, however, there has been a recent revolution in the scope of new information gleaned from such fossil finds.In Dinosaurs Rediscovered, leading paleontologist Michael J. Benton gathers together all the latest paleontological evidence, tracing the transformation of dinosaur study from its roots in antiquated natural history to an indisputably scientific field. Among other things, the book explores how dinosaur remains are found and excavated, and especially how paleontologists read the details of dinosaurs’ lives from their fossils—their colors, their growth, and even whether we will ever be able to bring them back to life. Benton’s account shows that, though extinct, dinosaurs are still very much a part of our world.

    Through the astonishing combined achievements of natural scientists worldwide, we now have a detailed account of how galaxies and stars, planets and living organisms, human beings and human consciousness came to be. And yet . . . we thirst for answers to questions that have haunted humanity from the very beginning. What is our place in the 14-billion-year history of the universe? What roles do we play in Earth's history? How do we connect with the intricate web of life on Earth?In Journey of the Universe Brian Thomas Swimme and Mary Evelyn Tucker tell the epic story of the universe from an inspired new perspective, weaving the findings of modern science together with enduring wisdom found in the humanistic traditions of the West, China, India, and indigenous peoples. The authors explore cosmic evolution as a profoundly wondrous process based on creativity, connection, and interdependence, and they envision an unprecedented opportunity for the world's people to address the daunting ecological and social challenges of our times.Journey of the Universe transforms how we understand our origins and envision our future. Though a little book, it tells a big story—one that inspires hope for a way in which Earth and its human civilizations could flourish together.This book is part of a larger project that includes a documentary film, an educational DVD series, and a website. For more information, please consult the website, journeyoftheuniverse.org.

    Morell probes the moral and ethical dilemmas of recognizing that even “lesser animals” have cognitive abilities such as memory, feelings, personality, and self-awareness--traits that many in the twentieth century felt were unique to human beings.By standing behaviorism on its head, Morell brings the world of nature brilliantly alive in a nuanced, deeply felt appreciation of the human-animal bond, and she shares her admiration for the men and women who have simultaneously chipped away at what we think makes us distinctive while offering a glimpse of where our own abilities come from.

    Beneath the frozen crusts of several of the small, ice-covered moons of Jupiter and Saturn lurk vast oceans that may have been in existence for as long as Earth, and together may contain more than fifty times its total volume of liquid water. Could there be organisms living in their depths? Alien Oceans reveals the science behind the thrilling quest to find out.Kevin Peter Hand is one of today's leading NASA scientists, and his pioneering research has taken him on expeditions around the world. In this captivating account of scientific discovery, he brings together insights from planetary science, biology, and the adventures of scientists like himself to explain how we know that oceans exist within moons of the outer solar system, like Europa, Titan, and Enceladus. He shows how the exploration of Earth's oceans is informing our understanding of the potential habitability of these icy moons, and draws lessons from what we have learned about the origins of life on our own planet to consider how life could arise on these distant worlds.Alien Oceans describes what lies ahead in our search for life in our solar system and beyond, setting the stage for the transformative discoveries that may await us.

    With his trademark clarity and humor, Holt probes the mysteries of quantum mechanics, the quest for the foundations of mathematics, and the nature of logic and truth. Along the way, he offers intimate biographical sketches of celebrated and neglected thinkers, from the physicist Emmy Noether to the computing pioneer Alan Turing and the discoverer of fractals, Benoit Mandelbrot. Holt offers a painless and playful introduction to many of our most beautiful but least understood ideas, from Einsteinian relativity to string theory, and also invites us to consider why the greatest logician of the twentieth century believed the U.S. Constitution contained a terrible contradiction--and whether the universe truly has a future.

    She reveals them to be curious, clever connoisseurs of their world, technologically inventive and ecologically adaptable. Above all, they were successful survivors for more than 300,000 years, during times of massive climatic upheaval.At a time when our species has never faced greater threats, we’re obsessed with what makes us special. But, much of what defines us was also in Neanderthals, and their DNA is still inside us. Planning, co-operation, altruism, craftsmanship, aesthetic sense, imagination... perhaps even a desire for transcendence beyond mortality.It is only by understanding them, that we can truly understand ourselves.

    Our Big Bang, our distant future, parallel worlds, the sub-atomic and intergalactic - none of them are what they seem. But there is a way to understand this immense strangeness - mathematics. Seeking an answer to the fundamental puzzle of why our universe seems so mathematical, Tegmark proposes a radical idea: that our physical world not only is described by mathematics, but that it is mathematics. This may offer answers to our deepest questions: How large is reality? What is everything made of? Why is our universe the way it is?Table of ContentsPreface 1 What Is Reality?

    New emphasis has been given to complexity, networks, and patterns of organisation, leading to a novel kind of 'systemic' thinking. This volume integrates the ideas, models, and theories underlying the systems view of life into a single coherent framework. Taking a broad sweep through history and across scientific disciplines, the authors examine the appearance of key concepts such as autopoiesis, dissipative structures, social networks, and a systemic understanding of evolution. The implications of the systems view of life for health care, management, and our global ecological and economic crises are also discussed. Written primarily for undergraduates, it is also essential reading for graduate students and researchers interested in understanding the new systemic conception of life and its implications for a broad range of professions - from economics and politics to medicine, psychology and law.
